Fix the intro sometimes lacking sound under NOMD5

I just decided to remove the conditional because I don't understand it and removing doesn't immediately break anything as far as I can tell. If this isn't a good idea, I can just look into separating some stuff with the intro ticker/drawer.

Does frameskipping still kick in when the framerate goes down to keep game logic running at the correct real-time speed? realtics is copied to counts which is used to determine how many times to call SV_Maketic(), which stores a frame of inputs in the tic buffer. (This is used in single-player too, I think.)
